I am having a hard time understanding the spec.

# field1: I guess a,b,c could be numbers: 0,1,2. If these are columns, then how many columns could there be?

# field2: some kind of comparison, compare what to what? is this a sort order?

# field3: I guess either a numeric or alpha-numeric string?

# field 4:"num" or "string" is redundant and not necessary?

# field4: I just guess that "filter" is a logical "AND" and that "APPEND" is a logical "OR"? But "and" to what and "or" to what?

# field5: I guess this is some priority, but to what? 

a  <=   0.3   num     filter     1
b  =    abc   string  append     3
c  <=   0.3   num     filter     2
